The Complete Guide
EPDM roofing has been a reliable option for flat and low-slope roof installation projects for nearly 60 years. If you’re contemplating an EPDM roof…
This guide is designed for you.
In this EPDM roofing guide ››
You will discover all the essential information:
Let’s commence with your EPDM roofing knowledge.
Ethylene Propylene Diene Monomer (EPDM) is a durable single-ply membrane composed primarily of propylene and ethylene.
Often referred to as a “rubber roof,” EPDM roofs can provide extended coverage for 50 years or more with appropriate maintenance.
Upon installation, a fully adhered EPDM roofing system exhibits high flexibility and remarkable versatility. However, rubber roofing is particularly suitable for low-slope roofs or flat commercial roof structures.
Comprising four distinct layers, EPDM roofing material ensures 100% waterproofing and does not contaminate rainwater runoff in any way.
You may be curious; What is EPDM roofing material composed of?
Let’s delve into it.
EPDM roofing comprises four layers, making it one of the most robust and enduring roof membranes available.
1. EPDM Elastomeric Base Layer
2. AFR Fire Retardant Middle Layer
3. FRM Polyester Fiber Reinforced Top Layer
4. Optional White EPDM Roofing Top Layer
Incorporating fully adhered vapor barriers, fiberglass, and polyethylene reinforcements, an EPDM roofing system can withstand some of the most challenging environmental elements, including high winds and hail storms.
Various installation methods exist. Some EPDM roofing systems are installed using a stone or paver ballast placed on top of the membrane.
EPDM roof membranes are supplied in rolled sheets that are wide and long, manufactured in three common thicknesses:
1. 45 Mil EPDM rubber roofing
2. 60 Mil EPDM rubber roofing
3. 90 Mil EPDM rubber roofing
Some manufacturers also provide a 75-mil EPDM membrane.
When contemplating membrane thickness for single-ply roofing installation…
Your roofer will take various factors into consideration when making a recommendation.
The thickness is directly related to the material’s resistance to damage.
Those located in high-risk zones for flying debris and severe storm conditions may prefer a robust thickness for their EPDM rubber roofing.
EPDM membranes are offered in black and white.
The color is determined by compounding various ingredients that enhance UV resistance.
For a black EPDM membrane, carbon black is added, converting UV rays into heat.
For a white EPDM membrane, titanium dioxide is typically used to reflect UV rays.
How crucial is EPDM membrane color?
Dark-colored roofing systems tend to absorb more heat, whereas white is more reflective of the sun’s rays.
The choice of color should depend on the specific needs and uses of the structure, as well as the region’s typical climate, considering that heating and cooling costs can accumulate.
Ethylene Propylene Diene Monomer is suitable for nearly any roof type and stands out as one of the most cost-effective options, ensuring decades of use. In addition to outperforming competitors, an EPDM roof installation offers several advantages:
EPDM rolls, being large and lightweight, cover more area quickly, facilitating swift installation. This efficiency translates to a more cost-effective solution for customers.
While structural failures are rare, EPDM's design makes repairs comparatively simple. Punctures and leaks often require only a few tools, seam tape, or seam overlays for effective and cost-efficient repairs.
EPDM rubber roofing, especially thicker options like 90 Mil or 60 Mil membranes with ballasted layers and external fleece reinforcement, provides exceptional resistance against hazards such as hail, snow, heavy wind, and falling trees. Thicker systems can prevent damage related to environmental elements up to 300 times better than thinner or lower-quality alternatives.
EPDM flat roof systems contribute to energy efficiency, whether in cold or warm climates. White EPDM roofing is beneficial in warmer regions, reflecting sunlight and lowering cooling costs, while those in colder climates might opt for black membranes to absorb heat and reduce heating expenses. Additionally, these materials boast a superior ozone-resistant rating, with a grade of 'A' in temperatures up to 100º F.
The lifespan of rubber roofing depends on quality installation, climate, and membrane thickness. In moderate climates with a low risk of penetrations, roofing experts may recommend 45 Mil EPDM rubber roofing membranes, typically lasting 12-15 years. Opting for a 90 Mil option can extend the lifespan to 25 years or more when installed with care.
TPO, short for thermoplastic polyolefin, is a roofing membrane composed of ethylene-propene and polypropylene. It is gaining popularity as a single-ply roofing option, similar to EPDM. Both TPO and EPDM are environmentally friendly, utilizing rubber and synthetics that adhere to insulation or are ballasted to create a durable protective roofing layer.
TPO membranes come in various thicknesses, impacting their longevity similarly to EPDM. This raises a common question: How long does TPO single-ply roofing last, and how does it compare to EPDM?
Reportedly, TPO single-ply membrane roofing systems have a lifespan of 20+ years, whereas EPDM can last 50 years or more. The newer TPO systems haven’t been around long enough to precisely determine their long-term durability and waterproofing capabilities.
Despite this, EPDM roofs have demonstrated proven long-term results. Key differences between these single-ply membrane roofing systems include:
1. Seam Construction:
2. Reflectivity:
3. Color Options:
4. Attachment Method:
5. Warranty Period:
